LED display is a very mature product in China. It displays text content from the beginning, and then pictures and texts are widely used in large-scale advertising, stage performances, exhibitions, sports, hotel lobby. And so on. LED screen has the advantages of large display area, high brightness, bright colors, easy assembly, high utilization of building space and low maintenance cost. However, it was limited to the technical bottleneck of LED display pixel spacing, close-range viewing and strong graininess, and failed to enter indoor high-end mainstream applications. In recent years, with the development of technology, the semiconductor manufacturing process has become more and more mature, making the LED display dot spacing smaller and smaller, and the resolution is getting higher and higher.
Among the big screen displays, the small-span LED wins the market's "killer"
All along, the splicing gap is an important factor affecting the visual experience. DLP splicing, liquid crystal splicing and PDP splicing have more or less seams due to physical characteristics. The development of technology can only make the seams shrink, but it can not disappear. Although the projection stitching is physically seamless, there is a fusion belt, which greatly tests the technical strength of the manufacturer, and needs regular adjustment to ensure the integration effect. The LED display has a large plasticity in splicing by virtue of the seamless splicing. At the same time, the small-pitch LED works well in terms of consistency, and the mature point-by-point correction technology makes the adjustment process simple and easy to maintain.
For small-pitch LEDs, the industry's recognition is almost one-sided. Small-pitch LEDs, with their own technological advantages, have begun to have the potential to impact the existing competitive landscape and enter high-end applications. The small-pitch high-density LED display (P2.5 and below) invaded the AV engineering field in 2013. It is the same as the high-brightness engineering projector large-screen display, DLP, PDP and LCD splicing screen, and has become a new force for large-screen display. For customers, the high-brightness, non-seamless, and small footprint of small-pitch LEDs are the places that attract them. The proportion of customers' active requests is on the rise. In 2013, the display of large halls More than 80% of customers will request LED screens as one of the options for comparison; the monitoring and production dispatching command center will be cautious, and about 30% of customers will consult the feasibility of using LED large screen solutions.
Small-pitch LEDs have a wide range of applications, impacting high-end applications
Small-pitch products are currently mainly for TV studios, power system monitoring centers, space command centers, force command centers, government administration halls, city monitoring centers, video conference rooms, dispatch rooms, airports, railway stations, media, and large and medium-sized enterprises. .
The goal of small-pitch LED manufacturers is clear, and gradually expand the brand influence from the high-end application market, and finally apply to the commercial market on a large scale. The strategic route of the relevant manufacturers is also very clear: first, the occupation part replaces the display products such as DLP rear projection and LCD splicing wall; secondly, the screen display of public places such as airports, shopping malls, hotels, etc., especially conference rooms. The main markets for small-pitch LED products are high-end command and control, monitoring rooms, conference rooms, etc., and these areas are just the main market for traditional large-screen splicing products, especially DLP, which has been deeply rooted in the past years.
Of course, the ultimate goal is to break the dominance of DLP, PDP and LCD, and reshuffle the entire big screen market. This goal is not so high, not to mention the advantages of small pitch LED without seams, easy maintenance, high brightness, etc., and small-pitch LED technology has been at the forefront of the market for domestic manufacturers.
3D/4K is easy to implement
The spacing of LED display screens is getting smaller and smaller, and the resolution is getting higher and higher, which makes the function and application field of the screen continue to be enriched and expanded. From the outside into the room, from the billboard to the TV set. In this process, the screen performance is also constantly improving, not only requires higher color, brightness, contrast, 4K, 3D and other concepts are also indispensable.
At the 2010 World Cup in South Africa, the 3D HD LED screen has entered the public eye. At the World Cup Fan Festival held in Saitama, Japan, it showed the world's largest 3D LED screen, which was 867 inches in size, 19.2 meters wide, 10.8 meters high, and 4.44mm pixel pitch. A total of 13,200 people wore 3D glasses to watch. 3D World Cup live broadcast.
Compared with other 3D screens, 3D LED screen pixels can emit light by themselves, with higher brightness, more vivid colors, higher contrast, ultra-thin and so on. It has natural and comfortable vision and a wider viewing angle. The prospects for specific places are broad. Today, the small-pitch screen plus 3D technology achieves better display performance, and with the development of naked-eye 3D technology, it also opens up more potential for 3D LED. Compared with 3D, with a pixel pitch of 1.2mm, it can achieve HD in 104 inches and 4k in 208 inches.
3D+4K+ small spacing makes LED display comparable to shoulder projection, flat panel display, DLP rear projection, and even the latter's voice is getting higher and higher.
